Scientific name: Chiasmia clathrata

May to September. Britain and Ireland. A small moth, the wings have latticed effect. Colours vary from yellow to white. Often rests with its wings raised like butterfly. Open habitats, gardens, heathland and chalk grassland.

The wings usually have a netted, or ‘latticed’, appearance, created by dark cross lines and veins on the paler ground colour on the upper and underside of the wings. Rarely, a melanic form can occur. Similar to the Common Heath and Netted Mountain Moth, but the resting posture of the former, with the wings held flat, should help to distinguish the Latticed Heath from that species. The markings of the Latticed Heath are also generally more defined than either of the other species.

Thye adults fly in sunshine and are also readily disturbed from vegetation. Thye also fly after dark. Very occasionally found in large numbers. The caterpillars can be found June to July and mid-August to September before overwintering as pupae.
